Diamonds are available in a diverse array of shapes and cutting styles. Here’s a look at some of the most popular diamond shapes:

1. Round

The round diamond is the most sought-after shape, accounting for over 75% of all diamond sales. Designed with 58 facets, this shape maximises brilliance and fire, creating a captivating sparkle.

2. Princess

The princess cut is a trendy square-shaped diamond, particularly favoured for engagement rings. Its pointed corners enhance its sparkle, making it a popular choice for many couples.

3. Cushion

Also known as the pillow cut, the cushion diamond features rounded corners and larger facets that amplify its brilliance. This classic shape combines elegance with modern appeal.

4. Oval

An elongated shape with rounded edges, oval diamonds are frequently used in solitaire engagement rings. Their unique shape creates an alluring appearance while elongating the wearer’s finger.

5. Marquise

Resembling a football, the marquise diamond boasts a pointed shape that can enhance the appearance of length in the wearer’s finger, adding an elegant touch.

6. Pear

Also referred to as the teardrop shape, the pear diamond blends the round and marquise shapes. This style is often featured in pendants and earrings, adding a touch of sophistication.

7. Emerald

The emerald cut is a rectangular-shaped diamond characterised by step-like facets. This distinctive cutting style creates a unique visual appeal and showcases the diamond’s clarity.

8. Asscher

Similar to the emerald cut, the Asscher cut is square with cropped corners and larger step-like facets. It offers a vintage aesthetic, highlighted by its pointed culet.

9. Radiant

Radiant diamonds can be square or rectangular with cropped corners. This brilliant cut combines the elegance of the emerald shape with the sparkle of a round cut.

10. Heart

As the name suggests, the heart-shaped diamond features a romantic silhouette, making it a popular choice for sentimental gifts, often seen in pendants and earrings.

Understanding Diamond Prices

Not all diamond shapes are priced the same. The cost of a diamond can vary based on factors such as quality, carat weight, and market demand. Generally, round brilliant cut diamonds command higher prices due to their popularity and the greater amount of rough diamond material that must be cut away during the manufacturing process.

Appearance and Size Perception

Diamonds of the same carat weight can look significantly different based on their proportions and shapes. Diamonds with larger surface areas or table sizes relative to their weight typically appear larger. Here are some shapes known for giving the illusion of greater size:

• Pear-shaped diamonds: The elongated shape and pointed end create the appearance of a larger diamond.
• Oval-shaped diamonds: Similar to pear shapes, ovals can look larger than other shapes of the same carat weight.
• Marquise-shaped diamonds: This football-like shape can also enhance the perception of size.
• Princess-cut diamonds: With their corners, princess cuts can appear larger than round diamonds if the depth is not over 70%.
• Emerald-cut diamonds: The step-cut facets of emeralds can make them seem larger, despite a smaller surface area than other shapes.

Choosing the right diamond shape not only enhances its beauty but also affects its perceived size and value. Whether you’re shopping for an engagement ring or a special piece of jewellery, understanding these shapes and their characteristics can help you make an informed decision.
